2.2.3, AIUI, does its own latency test at startup, and apparently seems to
detect a lag of some kind because something related to the video isn't quite
ready at the time it is getting everything initialized. I've been clearing
it and otherwise ignoring it. Its possible that the test could be moved
someplace else so it was done after all the initial screen redraws have been
done. But my coding expertise is fading as the years pile up, 73 of them now
and I never was up to the scale of a 32 bit linux framework, I did all of
mine on 8 & 16 bit stuff 20 years ago, usually in assembly or even entering
hex by hand in a monitor program. 1802/z80(spit)/and 6x09 stuff.

Humm, lemme see what I'm getting for this, crazy but I get identical timings,
but my cpu is a gigahertz slower.

Ignore it till 2.2.4 maybe?
